Abstract
A system and method for capacitive sensing comprise acquiring first capacitive sensor data and second capacitive sensor data from a plurality of sensor electrodes, and determining positional information from one or more input objects based on the first capacitive sensor data and the second capacitive sensor data. The plurality of sensor electrodes are driven with transcapacitive sensing signals for capacitive sensing during one or more transcapacitive sensing blocks to acquire the first sensor data. Each of the transcapacitive sensing signals is based on a respective one of a plurality of codes. Further, the plurality of sensor electrodes are operated for absolute capacitive sensing during one or more absolute capacitive sensing blocks to acquire the second capacitive sensor data.
